Patent number: 11940191Abstract: An expansion valve includes a housing, a threaded bush, a valve body, and a permanent magnet body. The threaded bush is arranged in the housing and extends along an axial direction. The threaded bush includes an external thread. The valve body is partially adjustably received in the threaded bush along the axial direction. The permanent magnet body is of a pot-shaped design and arranged in the housing. The permanent magnet body extends the threaded bush along the axial direction such that the valve body is partially received in a valve body receptacle surrounded by the permanent magnet body. The permanent magnet body surrounds a radially outside of the threaded bush in a common transition portion. In the transition portion, the permanent magnet body is firmly connected to the threaded bush via a latching connection.Type: GrantFiled: December 2, 2021Date of Patent: March 26, 2024Assignee: MAHLE INTERNATIONAL GMBHInventors: Jeffrey Van Delden, Matthias Lindenberg, Florian Wetzel

Patent number: 11906065Abstract: An electric valve may include an electric machine having a rotor and a stator, a valve body drivingly connected to the rotor, a valve seat cooperating with the valve body, a housing in which the rotor and the stator are arranged, a split pot arranged in the housing and fluidically separating a dry region from a wet region in the housing, and a spring assembly including at least one spring. The rotor may be arranged in the split pot. The stator may surround the split pot radially on an outside in a circumferential direction. The split pot may protrude beyond an axially outer front side of the rotor. The spring assembly may be coupled to the housing and may rest on the front side spaced apart from the housing such that the spring assembly mechanically impinges on the stator radially and axially.Type: GrantFiled: December 1, 2021Date of Patent: February 20, 2024Assignee: Mahle International GmbHInventors: Matthias Lindenberg, Jeffrey Van Delden, Florian Wetzel

Patent number: 11862393Abstract: A coil assembly, e.g., for use a valve, is disclosed. The coil assembly includes a coil arrangement including at least one electrically energizable coil, a coil ring carrier receiving the coil arrangement, and a flux conducting device for conducting magnetic field lines of a magnetic field provided via the coil arrangement. The flux conducting device includes a one-piece ferromagnetic pole ring that includes a ring base plate and a plurality of pole ring outer teeth arranged on an outer edge of the ring base plate and angularly bent over on fold-over outer edge regions of the ring base plate. The flux conducting device further includes a one-piece ferromagnetic counter-pole ring that includes a counter-ring base plate and a plurality of counter-pole ring outer teeth arranged on a counter-outer edge of the counter-ring base plate and angularly bent over on counter-fold-over outer edge regions of the counter-ring base plate.Type: GrantFiled: December 2, 2021Date of Patent: January 2, 2024Inventors: Jeffrey Van Delden, Matthias Lindenberg, Florian Wetzel

Patent number: 11828503Abstract: An electric valve, e.g., an electric expansion valve, for expanding a fluid, e.g., for a thermodynamic cycle, is disclosed. The electric valve includes an electric machine including a rotor and a stator interacting with the rotor during operation. A valve body is drive-connected with the rotor. The rotor, the stator, and the valve body are arranged in a valve housing. The valve housing, in an axial direction outside includes a bottom, and a connector projects axially from the bottom. At least one wing projects from the bottom, the at least one wing extending obliquely to the axial direction at least in portions and resiliently supports the bottom on the front side.Type: GrantFiled: December 1, 2021Date of Patent: November 28, 2023Inventors: Matthias Lindenberg, Jeffrey Van Delden, Florian Wetzel

Patent number: 11813922Abstract: An expansion valve for an air conditioning system of a motor vehicle may include a housing, a sensor, a stepping motor or a BLDC motor, a valve seat, and a valve body. The stepping motor or the BLDC motor may include a rotor and a stator surrounding the rotor. The rotor may include a permanent magnet body connected non-rotatably therewith. A separating can may be provided that surrounds the rotor and separates a wet region on a rotor side from a dry region on a stator side. The sensor may be connected with the separating can via an adhesive layer formed as a heat-conductive layer.Type: GrantFiled: November 30, 2021Date of Patent: November 14, 2023Inventors: Steffen Huebner, Matthias Lindenberg, Jeffrey Van Delden, Florian Wetzel

Patent number: 11363730Abstract: A housing for accommodating electrical components, in particular in a liquid pump, includes a housing pot including a bottom and a surrounding wall protruding from the bottom, as well as a housing cover closing the housing pot, including a shoulder protruding in the direction of the bottom. A simplified and cost-efficient production of the housing as well as an increased operational safety of the liquid pump are attained in that the housing cover forms a caulking connection with the surrounding wall of the housing pot with the help of at least one recess formed in the shoulder. The disclosure furthermore relates to a liquid pump including a housing of this type as well as a method for producing a liquid pump of this type.Type: GrantFiled: September 25, 2020Date of Patent: June 14, 2022Assignee: MAHLE International GmbHInventors: Johannes Diekmann, Robin Drefs, Sven B.
